Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100740, here are decompositions:

  • 7 + 100733 = 100740
  • 37 + 100703 = 100740
  • 41 + 100699 = 100740
  • 47 + 100693 = 100740
  • 67 + 100673 = 100740
  • 71 + 100669 = 100740
  • 127 + 100613 = 100740
  • 131 + 100609 = 100740

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 100,740 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 100740 first appears in π at position 119,164 of the decimal expansion (the 119,164ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
